Glass bottles powder’s impact on the technological characteristics of clay mixtures used for porcelain stoneware tiles
Abstract
This study aims to enhance porcelain’s physicochemical properties by adding glass powder as flux. Kaolinitic clay, sand, and glass powder were used to formulate six grades, fired between 1140-1260ºC for 2 h. Specimens were tested for shrinkage, mass loss, water absorption, density, porosity, and mechanical strength (three-point bending). Phases were identified by X-ray diffraction and compared with industrial porcelain. The incorporation of glass powder has enabled the reduction of the firing temperature, the enhancement of densification, the augmentation of mechanical properties, and the valorizations of glass waste. The grade with 20 wt% glass (P20) fired at 1220ºC (P20-122) showed the best results: 13% shrinkage, 3.93wt% mass loss, 0.2wt% water absorption, 0.4% porosity, density 2.4 g/cm3 (46.6%). Using glass powder not only improves porcelain quality but also contributes to recycling glass waste on an industrial scale.
